Although Sandnes only officially received town status (ladested) in 1860, its history as a settlement stretches back centuries. Originally, it was a small harbor and trading post at the southern tip of the Gandsfjorden. The city took its name, first mentioned in sources from 1723, from an old farm that was located on the site. Its formal founding in the 19th century was the result of separating from the larger parish of Høyland, which gave impetus to its independent development.
The rapid growth of Sandnes in the 19th and 20th centuries was driven by several key factors. First, its favorable geographical position turned it into an important transport hub connecting the coastal region with the fertile lands of Jæren, facilitating active trade. Second, rich clay deposits in the vicinity became the foundation for a thriving brick and pottery industry. Because of this, Sandnes earned the nickname "the pottery town" (pottemakerbyen) throughout Norway. The entrepreneurial spirit of the local residents also played a role: in addition to ceramics, the city became famous for bicycle manufacturing, solidifying its reputation as a major industrial center.
Sandnes' early identity was inextricably linked to industry. City life revolved around brickworks and pottery workshops, which shaped a specific lifestyle and the character of its residents—hardworking and enterprising. The economy was focused on the production and export of ceramic goods first, and then other industrial products, laying a solid foundation for the city's future prosperity.
